Artists' color display system

Abstract

An assortment of color elements is grouped within a plurality of color families which are organized in accordance with a circular color chart (FIG. 10A) and a columnar chart (FIG. 11-A). Except for the neutral-gray color family, a pair of boundary-hues respectively defines the extent of acceptable hue variation within each group, resulting in an included range of hue within each color family, and an excluded range of hue in between neighboring color families. Variant-hue charts enhance color comparison and selection within each main color family by displaying contrasting variations of all three color attributes, that is, value, saturation, and hue, within a single chart. Variant-hue charts also consolidate color elements into a compact format, and provide a graphical user interface for computer color selection.

Problems solved by technology

While the human eye is capable of perceiving color with great sensitivity, our color memory is short-lived.

Presently there are no color-appearance systems which adequately meet both the traditional and technological needs of today's fine artist.

There are ink-based color matching systems tailored to the printing industry and there are pigment-based systems used to specify industrial color matches, but both of these types of systems are too large and complex to be of practical use to the individual working with color on a smaller scale.

Also, because these systems are geared toward mass-production colorants, they are not easily adapted to the unique, more expensive, lightfast coloring materials used by artists.

Beyond some published color-mixing recipes and colored paper assortments, no tools are available to aid the artist in effectively dealing with the wide variety of color choices and new media he or she currently encounters, particularly in the realm of computer graphics.

Choosing a color within this type of GUI is not necessarily easy, however, since the color selection devices (called “color pickers”) usually comprise a representative sampling of the over 16 million colors that can be displayed on the computer screen (FIGS. 5-A, 6, and 8-A).

However, the known color palettes and swatch sets, containing relatively smaller assortments of discrete color elements, are not organized in formats with which most artists are comfortable.

However the 360° of this “artistic” RGB color wheel fails to provide a perceptually even distribution of hue (FIG. 36).

It also presents its hue gamut as a smooth, contiguous blend from which it is difficult to distinguish and select particularly desired hues.

Because it is subdivided into 72 contiguous hues it is an awkward organizational tool.

Consequently, the Munsell color system fails to adequately reflect the full range of pigments available to artists.

This is one of several color reference systems or multi-paged atlases which, by reason of their large quantity of finely-differentiated color elements (numbering in this case 5000), are too complex for general artistic use.

Since users generally prefer to select colors by seeing them, rather than by specifying numerical values, and since the smoothly-blended colors presented by some computer programs for color selection have the disadvantage of not allowing the user to visualize or pick a discrete color, the system of this patent utilizes a diagram of honeycomb-cells for displaying a small subset of predetermined colors.

The subset, however, comprises only 144 distinct colors, and such an abridged representation of the computer color gamut, while suitable for selecting colors for maps, charts, and business graphics, is inadequate for artistic use.

However the formulaic theory of color harmony on which these algorithms is based provides only trite color combinations unsuited to most fine arts applications.

While an efficient format for organizing basic, wet-media elements, this palette has no provision for arranging more comprehensive color assortments.

No accommodation is made, however, for including median primaries, that is primaries which have no perceptible warm or cool bias.

The Maratta system enjoyed a brief period of popularity, but was eventually rejected by Henri's students as being too technical.

It failed commercially, largely because of the perception that buying 35 premixed values of just ten different hues was neither economical nor convenient.

These include needless complexity (or, on the opposite hand, oversimplification), barely distinguishable color variations, inflexible organization, and a restrictive adherence to the limitations of a particular medium or technology.
